Ion Storage Group Research

The NIST Ion Storage Group carries out research on a wide range of topics in quantum information and precision measurement. Below is a listing of current research activities; click the links for additional information.

Trapped Ion Optical Clocks

We use trapped ions for precision metrology of optical frequency, which provides the basis for diverse applications from optical clocks to tests of fundamental physics and relativistic geodesy.

Quantum Computing with Trapped Ions

The coherent control of quantum-mechanical systems holds promise for revolutionizing computing. We develop new architectures and technologies to improve the fidelity and scalability of quantum control and readout for quantum computing based on trapped ions in radio-frequency traps.

Quantum Simulation and Sensing with Trapped Ions

We use magnetic and electric fields in a Penning trap to confine two-dimensional Coulomb crystals of ions. We can perform quantum simulations of many-body spin Hamiltonians in these systems, and can perform sensing of electric fields below the standard quantum limit using quantum mechanical squeezing.

Precision Measurement and Quantum Control of Trapped Molecular Ions

We use quantum logic techniques to prepare, control, and measure the rovibrational and electronic states of single trapped molecular ions using co-trapped atomic ions.

Quantum Networking with Trapped Ions

Quantum networks, a promising resource for computing and sensing, generate useful entanglement between locations separated by geographic distances. Our research is focused on generating high-fidelity remote entanglement between trapped ion qubits using telecom photons. The key enabling step is using an ion-trap-integrated fiber Fabry-Pérot cavity for efficient entanglement generation between ions and telecom photons.
